1 Claim.

This invention relates to skates of the tubular t e.

it aims to improve both the construction and methods of manufacture ofskates of this char- 5 acter with a View to reducing the expense ofmaking such articles While providing an exceptionally strong and sturdyconstruction. It is also an object of the invention to devise a lightweight skate which will be composed chiefly of sheet metal parts orsections.

The nature of the invention will be readily understood from thefollowing description when read in connection with the accompanyingdrawings, and the novel features will be particularly pointed out in theappended claim.

In the drawings,

Figures 1 to 5, inclusive, are perspective views illustrating,respectively, the dilferent parts, of a skate embodying this invention;

Fig. 6 is a side View of the complete skate;

Fig. 7 is a plan view on a larger scale of the skate shown in Fig. 6;

Fig. 8 is a front elevation of the skate shown in Figs. 6 and 7 andFigs. 9, 10 and 11 are sectional views approximately on the lines 9-9,1010 and 11-11, respectively, Fig. 6.

Referring first to Figs. 1 to 5, inclusive, it will be seen that thevarious skate parts there shown include a heel plate 2, toe plate 3, twoframe sections 4 and 5, respectively, and a runner 6. All of these partsexcept the runner may be made from sheet metal by means of suitablepunches and dies.

The two parts 4 and 5 are substantially symmetrical and are adapted,when properly secured together, to form what may be termed the frame ofthe skate. These sections form the two halves of a skate frame whendivided along its longitudinal median plane, but are so designed as tofacilitate their manufacture from sheet steel or certain of the morerecently developed alloys which are light in weight but have a highdegree of mechanical strength. In assembling the parts the two sections4 and 5 are brought together with their fiat faces abutting andcorresponding elements registering with each other, and they are weldedtogether in this relationship. This operation may be performed either byspot welding the parts at intervals or by making substantiallycontinuous welds to unite the flanges of the sections to each other. Thelower margins a and b of the sections 4 and 5 are offset in oppositedirections sufiiciently to provide a groove in the lower edge of theframe to receive the runner 6,

(Cl. 208167) I as will be evident from an inspection of Figs. 3, 4, 6and 10. When the two side sections have been welded together, the runnerthen is placed in this groove and is welded, either by spot welding orby substantially continuous welds, to the margins a and b. While therunner should be made of a high grade steel and may, if desired, behardened, it can be assembled with the other parts in this mannerwithout injury to the portion of the runner which will engage the ice.

The foot plate, which, in this case, is made in two pieces, is nextsecured to the upper end of the frame. It should be observed that whenthe sections 4 and 5 have been welded together the frame then includes arelatively large hollow rear post 7 having a fiat flanged top, a similarintermediate hollow post 8 and a smaller tubular toe post 9. It alsoincludes a tubular section 10 lying immediately above and parallel tothe runner 6. The heel plate 2 is welded to the upper end of the post 7,while the toe plate 3 is welded to the upper flanged ends of the posts 8and 9. These plates have suitable holes punched through them to receivethe screws and rivets by means of which the skate is secured to the soleof a shoe.

Due to the peculiar construction of the frame sections and the manner inwhich they are secured together, the frame may be made very light inweight while still having ample strength.

The invention thus provides a skate composed entirely of sheet metalparts except for the runner 6, the manufacturing operations being suchthat the expense for both materials and labor is relatively small. Inaddition the skate has the attractive appearance peculiar to skates ofthe tubular type while being far more economical to manufacture than thecommon tubular skates.

Having thus described my invention, what I desire to claim as new is:

A skate of the tubular type comprising a skate frame including twosimilar sections, welded together, and both extending longitudinally ofthe skate, said frame having a groove in its lower edge, a runnersecured in said groove and welded to said frame, said frame having atubular section parallel to and immediately above said groove andincluding two hollow posts extending upwardly from said tubular section,the frame also having a hollow post at its front end, a heel platewelded on the upper end of one of said posts, and a toe plate welded onthe upper ends of the other two posts, said welded plates being adaptedto functionally effect an additional securing means between said framesections.
